Fill the grid with digits 1 to 9, where in each row, every column and in each of the nine 3x3 boxes each digit occurs exactly once. The numbers in cells with an arrow occur in direction of the arrow exactly once.

Fill the grid with the digits 1 to 9. The digits represent the height of the skyscraper in each cell. Each row, column and 3x3-box has exactly one of each digit. In the marked diagonals no digit can appear more then once. The clues along the edges tell you how many skyscrapers you can see from that vantage point.

Put the numbers 1 through 9 into the hexagonal cells so that every line (of any length) contains every digit not more than once. The lines must contain consecutive numbers, i. e., if a line has five cells there can be 2, 3, 4, 5, 6 or 3, 5, 4, 2, 6 but not 3, 4, 1, 9, 8 in the cells.

The clues along the edges tell you how many skyscrapers you can see from that vantage point in the given direction.

Fill the grid with the digits 1 to 6. The digits represent the height of the skyscraper in each cell. Each row and column has exactly one of each digit. The clues along the edges tell you how many skyscrapers you can see from
that vantage point.

Fill the grid with the digits 1 to 5 and with parks. The digits represent the height of the skyscraper in each cell. Each row and column has exactly one of each digit and one park. The clues along the edges tell you how many skyscrapers you can see from that vantage point.
